CARBURETEFTFQR HYDROOARBON-ENGINES.

SPECIFICATION forming part of Letters Patent No. 772,979, dated October 25, 1904.

To all whon ifimcty concern:

Be it known that I, -BAP'rIs'rE VAuRs, a citizen ofthe Republic of France, residing at No. 33 Rue Quincampoix, Paris, in the Department of Seine, France, have invented new and useful'I'mprovements in Carbureters for Hydrocarbon-Engines, of which the following is a specification.

The present invention relates to a novel arrangement for effecting the admission of carbureted air into gasengines making use of the so-called pulverization-carbureters.

One of the features of this invention consists in the employment of a single handle withdouble regulating-ring, which allows of varying the carburization by acting as requisite and with the same stroke upon the airsituated atthe rear of this apparatus.

obvious that the air admitted through the ting air in considerableproportions through the ports situated in front of the pulverization concurrently with a simultaneous admis-. sion of air through-the carburization-ports It is ports behind the pulverization apparatus is carbureted from the time of its passage over the said apparatus and carries over the liquid in the stateof tiny drops; but themixture thus formed does not become really rich and dry until it is met by a large and measured quantity offresh air coming from the ports situated in the front of the apparatus. This being ascertained, it has been found advantageous to arrange on the double regulatingring and on the parts which it covers air-ports in the front of and at the rear of the pulverization apparatus in connection with one another in such a manner as to fulfil the following working conditions: First, the simultaneous opening of the ports at the front and the rear; second, the progressive regulating of the port at the front, the ports at the back being kept fully opened; third, the simultaneous closing of the ports both at the front and the rear.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view, partly in longitudinal section, of the regulating device applied to a pulverization-carbureter with aconstant level 5 5 and float. Fig. 2 is a similar view in longitudinal section of the regulating device applied to a pulverization-carbureter witha constantly-full reservoir. Fig. 3 is a transverse section on the lines 1, 2, 8, and 4t of Fig. 2. Fig. 4 is a longitudinal section of the double regulating-ring. Fig. 5 is a longitudinal section of the new double regulatin'gring,which is provided with a protective jacket against The pulverization apparatusa opens into the pipe 6 at the commencement of the jun,c tion-piece 6, connecting the pipe 6 to the admission-tube f by means of the nut g. The pipe 6 is provided with two ports 0 for the admission of air. The piece 6 has asingle port (Z, which forms the only orifice for the admission of fresh air in the front of the pulverization apparatus.

' The regulating-handle It bears the ring 71, having two diameters. In this ring there are two apertures lrfor regulating the ports 0 and an aperture j for regulating the port d. The

aperture 7' of the ring is of the same size,as

On the other hand,

the port (Z of the piece 6. the apertures ]i} of the ring are longer than the ports 0 of the pipe '5. The circumferential length of an aperture is is equal to the sum of the circumferential lengths of one port 0 and of the port cl. It will be seen from Fig. 5

is moved to the left, the ports 0 and the port (Z are thus simultaneously closed, which gradually diminishes the speed of the motor until it stops altogether. It should be observed, however, that in the position shown in Fig. 3that is, When the ports 0 d are fully opened the stoppage of the motor can be likewise effected by admitting fresh air without carburization, as the port (Z is arranged to suffice When entirely uncovered for filling the admission-tube, Which neutralizes the effect of the carburization.

Inside the junction-piece there is intended to be placed a piece of Wire-gauze '2', Fig. 2, preferably cone-shaped, the point turned toward the pulverization apparatus for the purpose of assisting the mixing of the explosive mixture. There may also be placed round the regulating-ring a protective jacket for preventing dust from entering into the apparatus and consisting of bushes s, surrounding the ring, Fig. 5, and inclosing a piece of Wire-gauze 25. These bushes are of course provided With apertures corresponding With those of the ring.

This device may be suitably applied to any pulvkerization-carbureter. For example, Fig.

I shows the invention applied to a pulverization-carbureter with constant level and with inlets Z' in said ring adapted to cover or uncover the fore ports (a, the air-inlets j in said ring adapted to cover or uncover the rear ports (Z, said ring and inlets being so disposed that the rear ports can be maintained fully open while the front ports are progressively closed, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
